What it is
When a gearbox has internal damage, such as failed bearings, broken gears or worn synchros, it needs a proper repair rather than a quick fix. Sometimes the better answer is to swap the gearbox for another unit.
A gearbox swap can also be part of a bigger project, such as an engine swap or a build, where the gearbox has to suit the engine, the mounts and the rest of the drivetrain.
For a worn clutch or a smaller gearbox fault on an everyday car, see our clutch and gearbox repairs.
